To all whom it may concern:

Be it known that I, Fnnomc l). Oonnn, a I citizen of the United Statesof America, and a resident of Bayonne, county of Hudson, and State ofNew Jersey, have invented certain new and useful Improvements inCoupling-Bolts, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part thereof. i

My invention relates to improvements in coupling bolts, and particularlyto a type of coupling bolt having relatively movable parts wherein, whenthe nut employed thercwith is removed, the parts maybe moved to aposition in which the bolt may be inserted head first through anopening, and after the parts have been returned to their normal positionto receive the nut, the head cannot be withdrawn through the opening.

, My invention consists in certain novel details of construction andcombinations of parts, such as will be specifically pointed outhereinafter, and in order that my invention will be fully understood 1will now proceed to describe certain embodiments thereof, havingreference to the accompanying drawings illustrating the same, and willthen point out the novel features in claims.

In the drawings: Figure l is a view iii side elevation of a boltconstructed in accordancewith my invention, showing the same in use.Fig. 2 is a view in side elevation of the bolt removed from the work,the point of view in Fig. 2 being at right angles to the point of viewin Fig. 1. Fig. 3 is a viewin central vertical section throu h the bolt.Fig. 4 is a view, similar to Fig. 2 in side elevation of the bolt, butshowing the same, without the nut, and with the tongue moved from itsnormal position in the bolt stem. Fig. 5 is a .view in central section,similar to Fig. 3, of a slightly modified form of the bolt. Fig. 6 is aview in side elevation, similar to Fig. 2, of a further modification.Fig. 7 is a face view of the disassembled bolt portions of the form Inthe construction shown in Figs. 1. to inclusive, the bolt comprises amain body portion consisting of a screw threaded shank I0 and a turnedover head portion 11 and a removable tongue consisting of' a shank 12and a head portion 13 projecting at right angles therefrom. The shank l2(if-the tongue is fitted into a slot or cutaway portion 14 of the shank1'- of the body portion of the holt, and the head portion 13 of thetongue projects in a direction opposite to the direction in which thehead portion 11 of the bolt projects so that the two portions lhand 13togethcrf orm the bolt head. A shoulderedportioii 15"at 'the end of theshank rests against the body portion, by which the tongue is preventedfrom moving longitudinally in thedirection of the arrow in Fig. 3. A.nut 17 is fitted to the screw threaded portion of the shank 10, anditwill be understood that the width of the shank portion 19 of thetongue is such as to permit the nut to in freely moved upon the shank10; in other worc s, the width of the "tongue is no greater than theInner diameter of the screw threads. When it is desired to apply thebolt, the nut 17.is first unscrewed from the shank 10, and the tongue isthen removed from its position in the cut-away port-ion. 13. The headportion 11 is then insertedthrough the opening (18, Fig. 1) in the work,and thereafter? the extremity of the head portion 13 of the ,tongue ispresented to the opening 18 while the rear portion thereof is insertedinto the slot or cutaway portion 14 of the shank 10, the tongue beingthen swung into place so that the shank 12 thereof is received whollywithin the slot 14 and thehead portion caused to project upon the rearface ofthe work in the position in which it appcars'in Fig. 1. The nutis now screwed into place upon the shank of the bolt and is tightenedup. The nut prevents lateral displacement of the. tongue with respect tothe bolt, and longitudinal displacement thereof is prevented by theengagement. of the shoulder 15 with the abutment l6; hence when the nutis screwed up tight, relative movement of the parts is impossible, andit will be impossible for the head of the bolt to be withdrawn throughthe opening in the work.

To remove the bolt, it would only be neces sary to remove the nut whenthe tongue and b0 y portion can be disassembled, and the parts readilywithdrawn.

This form of coupling bolt is very useful for many purposes in themechanical art, and it is partici llarly useful in sheet metal anabutment 16 in v work Where it so often happens that ready access canonly be had to one side of the Work. It is also useful Where undercutopenings are used to provide for concealed bolt heads.

It Will be readily understood that a bolt of this description may bemade in various forms, and in Fi z 5, I have shown a form in which thecut-away portion in the shank of the bolt does not extend clear throughthe bolt, but extends for a portion of the distance only. The tongue isthen, of course, made proportlonately narrower as shown in F g. 5.

In Figs-(S and 7, I have shown still another construction in which thebody por- $1011 of the bolt 18 madein two halves, that is to say,'thebody portion of thcconstruction shown in Fig. 2 is divided upon itsmedial line.

iVhat I claim is:

1. A coupling bolt comprising two independent and separable membersarranged laterally 1')'10V\l)l with respect to each other,

but longitudinally coengaged whereby they freely engaging the said screwthreaded portion and oti'ier said portion to pre vent relative lateraldisplacement thereof.

5. coupling boit comprising a body portion having a screw threaded shankand part of head, the shank having a longitudinal slot therein forreceiving a tongue, and a tongue titted between the Walls of the uponthe said slot and arranged-to slide longitudi nally' therein in onedirection, the said tongue being provided vrith the other portion of thehead of the boltv 4 In a coupling bolt, with a body portion coi'isistingof a screw threaded shank and a portion projecting therefromat one endto form partoi": the head, the said shank hav 1;; a slotted portiontherein terminating in an. abutment, of a tongue having a shank fittedto the said slotted portion and provided with a shoulder which engagesthe abutment, and havii a portion constituting ai'iothcr part oftliesaid head of the bolt.

In a coupling, bolt, the combination with a screw threaded body portionhaving a slot which extends all the way across the same and throughoutnearly but not quite all the length thereof, and a tongue whose widthnot greater than the-smaller diameter of the screw threaded portion,titled in the said slot, the said body portion and tongue having"con'iplementary head portions.
